Which of the following is the best description for the behaviour of bromine in the reaction given below ?
$${H_2}O + B{r_2} \to HOBr + HBr$$
A.
Proton acceptor only
B.
Both oxidized and reduced
C.
Oxidized only
D.
Reduced only
Answer :
Both oxidized and reduced
Solution :
$${H_2}O + \mathop B\limits^0 {r_2} \to HO\mathop {Br}\limits^{ + 1} + H\mathop {Br}\limits^{ - 1} $$
Thus here oxidation number of $$Br$$ increases from 0 to +1 and also decreases from 0 to –1. Thus it is oxidised as well as reduced.
